Temperature dependence of space charge behavior in silicone

The generation of space charges in a silicone elastomer has been characterized under DC voltage as a function of the temperature using the LIPP method. Both heterocharges and homocharges have been observed depending on the field magnitude, polarization duration and temperature. Heterocharges appear in less stressed conditions. Then, homocharges take place of these heterocharges. The phenomena depend on the electrode polarity.
